Lookin' to add more traps, tricks, and jokes to my game. I know of a number of books out there, but have no experience with any of them. Any feedback/ideas are appreciated.
For traps I would suggest Traps and Treachery I and II from Fantasy Flight Games. They have some riddles and puzzles in the books as well. I prefer the first one over the second but I like both of them. You can get the PDF versions of them for only $5 US. The print versions were also on sale for $5 US from FFG directly for a while. I'm not sure if there are any copies left now though.
Wurst of Grimtooth's Traps from Necromancer Games is another good one for traps.
Goodman Games have a book called Lethal Legacies which is also about traps. I don't own it but I am looking up picking up the PDF.
There really isn't a good tricks and riddles book for Third Edition. Traps and Treachery I has a few, but most aren't that great. It does, however, have a nice trap selection, so it's worth it for the good traps and the adequate(but still better than other 3E stuff) puzzles.
